The meal is salmon with arugula, avocado and olive oil, finished with a square of dark chocolate. It can fit into a heart-conscious way of eating, but the available evidence does not show that this particular dinner—or any single meal—prevents a heart attack.
What is the “anti-heart attack” meal?
The exact-title article identifies five ingredients: salmon, arugula, avocado, olive oil and dark chocolate. Together, they make a flavorful meal built around fish, greens and plant foods. The “anti-heart attack” label is a catchy description, not a proven medical effect.
The article says, “No meal prevents a heart attack.” That distinction matters: the prevention evidence discussed here concerns dietary patterns followed over time, not a single plate or a special combination of ingredients.

PREDIMED was a multicenter trial in Spain involving 7,447 adults aged 55–80 who were at high cardiovascular risk but had no cardiovascular disease when they enrolled. Participants received advice to follow a Mediterranean diet supplemented with extra-virgin olive oil, a Mediterranean diet supplemented with mixed nuts, or a control diet that advised reducing dietary fat. The trial followed these dietary approaches for roughly five years and measured a combined outcome of myocardial infarction, stroke and cardiovascular death. The corrected 2018 report found fewer major cardiovascular events in the Mediterranean-diet groups than in the control group.
#1 Best Overall
The investigators reported an approximately 30% relative difference in that combined endpoint. It describes the result for the tested diets and high-risk study population; it is not a 30% personal reduction in heart-attack risk, nor a result for the salmon-and-arugula meal. The trial also identified protocol deviations, including departures from random assignment, and revised its estimates. A contemporaneous NEJM commentary noted that the relative reduction remained after correction while acknowledging other potential sources of bias.
Why the 30% figure is not a heart-attack guarantee
PREDIMED’s primary outcome combined three kinds of events. The 2019 ACC/AHA primary prevention guideline notes that the combined result was largely driven by stroke; the study did not show a significant improvement over the control group in mortality or myocardial infarction. So it is inaccurate to present the headline figure as proof that this meal—or even the tested diet—specifically prevents heart attacks.
Rank #2
What you can reasonably take from the meal
The guideline describes Mediterranean and plant-based eating patterns rich in vegetables, fruit, nuts and legumes, and preferably including fish, as associated with lower risk. That supports discussing an overall pattern of eating, not assigning a proven prevention effect to each ingredient on this plate.

- It can be a heart-conscious choice. The ingredients are compatible with the broad dietary pattern discussed by the guideline.
- It is not a prescription. The cited evidence does not establish that every patient should eat this exact meal, or that a clinician recommends it to all patients.
- It is not a substitute for care. A meal cannot replace an individualized prevention plan or treatment from a health professional.
